Stripping of Non-Printable Chars in the Who Is Online Page

Noticed that after changing our site and HTML be to UTF-8 compliant per HTML5 standards, we started to see unprintable chars in the country and city name from the geoip database which converts IP addresses to country and city names. So, I just added this code to that PHP plugin which seems to do the trick:

Code:

if($record->city){ 
    $clean = preg_replace('/[\x00-\x1F\x7F]/u', '', $record->city . ", " . $record->country_name); 
     $userinfo['geoip_country_name'] = $clean; 
  } 
else { 
    $clean = preg_replace('/[\x00-\x1F\x7F]/u', '', $record->country_name); 
    $userinfo['geoip_country_name'] = $clean; 
  }

I did a check and seems that problem has been solved, or at least a bandaid fix to another issue I don't have time to look into at this time.

html::html5::parser::error

HTML::HTML5::Parser::Error(3pm) 			User Contributed Perl Documentation			   HTML::HTML5::Parser::Error(3pm)

NAME

       HTML::HTML5::Parser::Error - an error that occured during parsing

DESCRIPTION

       Note that HTML::HTML5::Parser is not a validation tool, and there are many classes of error that it does not care about, so will not raise.

       The "error_handler" and "errors" methods of "HTML::HTML5::Parser" generate "HTML::HTML5::Parser::Error" objects.

       "HTML::HTML5::Parser::Error" overloads stringification, so can be printed, matched against regular expressions, etc.

   Constructor
       "new(level=>$level, type=>$type, token=>$token, ...)"
	   Constructs a new "HTML::HTML5::Parser::Error" object.

   Methods
       "level"
	   Returns the level of error. ('MUST', 'SHOULD', 'WARN', 'INFO' or undef.)

       "layer"
	   Returns the parsing layer involved, often undef. e.g. 'encode'.

       "type"
	   Returns the type of error as a string.

       "tag_name"
	   Returns the tag name (if any).

       "source_line"
	     ($line, $col) = $error->source_line();
	     $line = $error->source_line;

	   In scalar context, "source_line" returns the line number of the source code that triggered the error.

	   In list context, returns a line/column pair. (Tab characters count as one column, not eight.)

       "to_string"
	   Returns a friendly error string.
